TAP FOR LIQUID CONTAINERS.

Application filed July 13, 1923. Serial No. 651,407.

7 '0 all whom it may concern:

Be it known that I, MARY A. DARRow, citizen of the United States, residing at Miami, Florida, have invented certain new and useful Improvements in Taps for Liquid Containers, of which the following is a specification.

The present invention relates to a tap for liquid containers, especially milk containers of the sanitary type now coming into quite general use. The tap is particularly designed for decanting the cream from such containers. The invention will be described with reference to the accompanying drawings in which,

Fig. 1 is a perspective of the tap;

Fig. 2 is a perspective of the tap in operative position in a container of the type above referred to; and

Fig, 3 is a longitudinal section through the tap and the upper portion of the container.

Referring now to the drawings, 1 represents a conioally shaped tubular member, which is provided near its large end with a disk shaped stop 2. According to the invention this stop is arranged at an angle to the axial line of the member 1, which may be varied according to conditions which will be explained hereinafter. In the top wall of the tubular member 1 apertures 3 and 4 are provided, these apertures lying between the disk and the point of the tubular member. Beyond the disk a downwardly extending spout 5 is joined to the member 1.

The parts as described are conveniently made of light weight sheet metal.

The type of milk container for use with which this tap is especially designed consists of a circular base member having mounted thereon side walls having the form of the frustum of a cone and is made of slightly still waxed paper. When the container is filled the upper edges of the side walls are brought together and sealed by means of a light metal clip. The configuration of the container when sealed will be readily understood from Figs. 2 and 3 in which 7 indicates the side walls of the container and 6 the metal capping piece.

Since the walls of the container are of translucent material the separating line of the milk and cream will be readily visible when the container is held to the light. For the purpose of separating the cream, therefore, it is only necessary to push the tap through the wall at the line of division. Since the member 1 is tapered to a point it will have a constant forcing tendency on the container wall during insertion, thereby making a tight joint. The disk 2 serves as a stop for abutting the side wall and also as positioning means for the member 1, as will be explained.

It is desirable, in order to prevent passage of any milk while atthe same time drawing off all the cream, that the member 1 be inserted on the line of separation on a substantially horizontal line. It will be seen especially from Fig. 3 that the sides of the container are inclined considerably to the horizontal and if the disk 2 was arranged at right angles to the axial line of the member 1 the point thereof, together with the aperture 4, would dip considerably below the horizontal when the stop and the container wall were in contact. For the purpose, therefore, of maintaining the tap in its correct position the disk 2 may be arranged at an angle to .the axial line of the member 1 which is substantially equal to the angle between the side wall 7 and its base. This modification is desirable since the most convenient point for insertion of the tap is in one of the comparatively flat faces caused by the straight clip 6 and it is the angle which these faces make with the horizontal to which the angle of the disk 2 with the member 1 conforms, as described above. I

The utility and cheapness of construction of this tap will make it of large appeal to dairy companies as an advertising medium, and the disk 2 can be made of suitable size for the reception of advertising matter which can be readily stamped or printed thereon.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

A tap for containers having a thin easily puncturable side wall angularly inclined to the horizontal, comprising a pointed, conically shaped tube adapted to be pushed through said side wall, apertures in the u per wall of said tube, a flange on said tu e inclined to the axial line thereof at an angle substantially supplemental to the angle of inclination of said side wall, whereby said flange is adapted to abut against said side wall for maintaining said tube in the substantially horizontal position, said apertures being positioned to be within said container when said stop abuts said side wall. 10 The foregoing specification signed at Miami, Florida, this 28th day of June, 1923.
